It is likely to increase calls for further measures to be introduced both in and around stadia after the security was criticised in Marseille.

UEFA are concerned trouble could flare up again next week when Russia take on Slovakia in Lille on Wednesday and England face Wales in Lens on Thursday with supporters likely to converge.

A statement from European football's governing body said: “The UEFA Executive Committee would like to express its disgust for the violent clashes which occurred in the city of Marseille.

“Such unacceptable behaviour by so-called supporters of the national teams of England and Russia has no place in football, a sport we must protect and defend.

“The UEFA Executive Committee has warned both football associations that - irrespective of any decisions taken by the independent disciplinary bodies relating to incidents inside the stadium - it will not hesitate to impose additional sanctions on the Football Association (FA) and the Russian Football Union (RFU), including the potential disqualification of their respective teams from the tournament, should such violence occur again.

“We urge both the FA and the RFU to appeal to their supporters to behave in a responsible and respectful manner.

“We would also like to publicly voice our support for the work of the French Authorities and security forces for their efforts to deliver a safe and secure tournament in challenging circumstances.”
